I doubt it. I listed him for 1 million after I got eliminated from BBM. Had a few looks and a couple of people bookmarked him. I just relisted him for 250K higher just to be a jerk. But you never know.
Fabre listed for 500k and sold for over 1 million. That was a short, but sweet bidding war.
I think players become less valuable as their salaries rise. If you can afford him, you probably have developed someone as good or better than him already. There's always the hope that someone is desperate to win their league, but it's a steep price to pay.
It seems like the best way to make money is to develop young players and sell them at 21-22. They usually have low enough salaries that you can entice a drunk Italian 4th division manager to spend a lot. Or in this case, a Polish one.
